BACKGROUND

PKCι and PKCζ (accession numbers NM_002740 and NM_002744 respectively)together define the atypical sub-class of the protein kinase C(PKC)family. The aPKCs are structurally and functionally distinct from theother PKC sub-classes, classic/conventional and novel, as theircatalytic activity is not dependent on diacylglycerol and calcium (Ono,Y., Fujii, T., Ogita, K., Kikkawa, U., Igarashi, K., and Nishizuka, Y.(1989). Protein kinase C zeta subspecies from rat brain: its structure,expression, and properties. Proc Natl Acad Sci USA 86, 3099-3103).Structurally, PKCι and PKCζ contain a C-terminal serine/threonine kinasedomain (AGC class) and an N-terminal regulatory region containing a PhoxBem 1 (PB1) domain involved in mediating protein:protein interactionscritical for aPKC function. At the amino acid level the aPKCs share 72%overall homology, however, the kinase domains share 84% identity anddiffer in the active site by just a single amino acid. This strikinghomology suggests an ATP-competitive ligand would not be expected toexhibit significant aPKC isoform selectivity.

The aPKCs have been implicated in a diverse number of signallingpathways, demonstrating both redundant and distinct signallingfunctions. Both isoforms have emerged as central players in themechanisms that regulate the establishment and maintenance of cellularpolarity in multiple cell types (reviewed in Suzuki, A., and Ohno, S.(2006). The PAR-aPKC system: lessons in polarity. J Cell Sci 119,979-987). Genetic dissection of their functions using knockout mice havealso revealed preferential roles for PKCζ in the regulation of NF-kBsignalling (Leitges, M., Sanz, L., Martin, P., Duran, A., Braun, U.,Garcia, J.F., Camacho, F., Diaz-Meco, M. T., Rennert, P. D., and Moscat,J. (2001). Targeted disruption of the zetaPKC gene results in theimpairment of the NF-kappaB pathway. Mol Cell 8, 771-780), and PKCι ininsulin secretion and action (Farese, R. V., Sajan, M. P., Yang, H., Li,P., Mastorides, S., Gower, W. R., Jr., Nimal, S., Choi, C. S., Kim, S.,Shulman, G. I., et al. (2007). Muscle-specific knockout of PKC-lambdaimpairs glucose transport and induces metabolic and diabetic syndromes.J Clin Invest 117, 2289-2301). In addition, both isoforms have beenimplicated in the pathogenesis of cancer making a strong case for theinhibition of the aPKCs as a novel therapeutic avenue.

PKCι is a known oncogene in non-small cell lung cancer (NSCLC). In onestudy it was shown to be overexpressed in 69% of NSCLC cases at theprotein level. Consistent with this, the PKCι gene (PRKCI residing onchromosome 3q26) was shown to be amplified in 36.5% of NSCLC tumoursexamined, including 96% of the squamous cell carcinoma sub-type (Regala,R. P., Weems, C., Jamieson, L., Khoor, A., Edell, E. S., Lohse, C. M.,and Fields, A. P. (2005b). Atypical protein kinase C iota is an oncogenein human non-small cell lung cancer. Cancer Res 65, 8905-8911).Amplification of 3q26 has also been reported in 44% of ovarian cancers,including >70% of serous epithelial ovarian cancers where 3q26amplification is translated into increased PKCζ protein expression.Moreover, increased PKCι expression is associated with poor prognosis inNSCLC and ovarian cancer where it may serve as a diagnostic biomarker ofaggressive disease (Eder, A. M., Sui, X., Rosen, D. G., Nolden, L. K.,Cheng, K. W., Lahad, J. P., Kango-Singh, M., Lu, K. H., Warneke, C. L.,Atkinson, E. N., et al. (2005). Atypical PKCiota contributes to poorprognosis through loss of apical-basal polarity and cyclin Eoverexpression in ovarian cancer. Proc Natl Acad Sci USA 102,12519-12524; Zhang, L., Huang, J., Yang, N., Liang, S., Barchetti, A.,Giannakakis, A., Cadungog, M. G., O'Brien-Jenkins, A., Massobrio, M.,Roby, K. F., et al. (2006). Integrative genomic analysis of proteinkinase C(PKC) family identifies PKCiota as a biomarker and potentialoncogene in ovarian carcinoma. Cancer Res 66, 4627-4635). 3q26amplifications have been observed in many other cancers includingoesophageal squamous cell carcinoma (Yang, Y. L., Chu, J. Y., Luo, M.L., Wu, Y. P., Zhang, Y., Feng, Y. B., Shi, Z. Z., Xu, X., Han, Y. L.,Cai, Y., et al. (2008). Amplification of PRKCI, located in 3q26, isassociated with lymph node metastasis in esophageal squamous cellcarcinoma. Genes Chromosomes Cancer 47, 127-136) and breast cancer(Kojima, Y., Akimoto, K., Nagashima, Y., Ishiguro, H., Shirai, S.,Chishima, T., Ichikawa, Y., Ishikawa, T., Sasaki, T., Kubota, Y., et al.(2008). The overexpression and altered localization of the atypicalprotein kinase C lambda/iota in breast cancer correlates with thepathologic type of these tumors. Hum Pathol 39, 824-831) suggesting thatPKCι may also participate in the pathogenesis of these diseases.

In NSCLC the primary function of PKCι is to drive transformed growth viaa Rac1/PAK/MEK/ERK signalling axis. However, PKCι also functions inNSCLC survival, resistance to chemotherapy, and invasion via distinctpathways (reviewed in Fields, A. P., and Regala, R. P. (2007). Proteinkinase C iota: human oncogene, prognostic marker and therapeutic target.Pharmacol Res 55, 487-497). In ovarian cancer transformed growth iscorrelated with deregulated epithelial cell polarity and increased cycleE expression (Eder et al., 2005) suggesting that PKCι can influence thecancer phenotype through multiple mechanisms. Compelling evidence hasemerged to suggest that inhibition of PKCι may be a useful therapeuticapproach to combat tumours characterised by increased PKCι expression.In transgenic models, mice with elevated PKCι activity in the colon aremore susceptible to carcinogen-induced colon carcinogenesis, andexpression of a kinase-dead mutant of PKCι blocks the transformation ofintestinal cells by oncogenic Ras (Murray, N. R., Jamieson, L., Yu, W.,Zhang, J., Gokmen-Polar, Y., Sier, D., Anastasiadis, P., Gatalica, Z.,Thompson, E. A., and Fields, A. P. (2004). Protein kinase Ciota isrequired for Ras transformation and colon carcinogenesis in vivo. J CellBiol 164, 797-802). Finally, genetic or pharmacological inhibition ofPKCι by a gold derivative—aurothiomalate (ATM)—blocks the growth ofNSCLC cells in soft agar and significantly decreases tumour volume inxenograft models of NSCLC(Regala, R. P., Thompson, E. A., and Fields, A.P. (2008). Atypical protein kinase C iota expression and aurothiomalatesensitivity in human lung cancer cells. Cancer Res 68, 5888-5895;Regala, R. P., Weems, C., Jamieson, L., Copland, J. A., Thompson, E. A.,and Fields, A. P. (2005a). Atypical protein kinase Ciota plays acritical role in human lung cancer cell growth and tumorigenicity. JBiol Chem 280, 31109-31115).

Despite the high degree of similarity between aPKC isoforms, the role ofPKCζ in cancer is distinct from that of PKCι. PKCζ plays a role in NSCLCcell survival by phosphorylating and antagonising the pro-apoptoticeffects of Bax in response to nicotine (Xin, M., Gao, F., May, W. S.,Flagg, T., and Deng, X. (2007). Protein kinase Czeta abrogates theproapoptotic function of Bax through phosphorylation. J Biol Chem 282,21268-21277). PKCζ activity has also been linked to resistance against awide range of cytotoxic and genotoxic agents. For instance, in humanleukaemia cells, overexpression of PKCζ confers resistance against1-β-D-arabinofuranosylcytosine (ara-C), daunorubicin, etoposide, andmitoxantrone-induced apoptosis (Filomenko, R., Poirson-Bichat, F.,Billerey, C., Belon, J. P., Gamido, C., Solary, E., and Bettaieb, A.(2002). Atypical protein kinase C zeta as a target forchemosensitization of tumor cells. Cancer Res 62, 1815-1821; Plo, I.,Hernandez, H., Kohlhagen, G., Lautier, D., Pommier, Y., and Laurent, G.(2002). Overexpression of the atypical protein kinase C zeta reducestopoisomerase II catalytic activity, cleavable complexes formation, anddrug-induced cytotoxicity in monocytic U937 leukemia cells. J Biol Chem277, 31407-31415). Furthermore, inhibition of PKCζ activity throughexpression of a kinase-dead mutant sensitises leukaemia cells to thecytotoxic effects of etoposide both in vitro and in vivo (Filomenko etal., 2002). Atypical protein kinase C regulates dual pathways fordegradation of the oncogenic coactivator SRC-3/AIB1. Mol Cell 29,465-476), and both of these proteins have been postulated to play a rolein tamoxifen resistance in breast cancer (Iorns, E., Lord, C. J., andAshworth, A. (2009). Parallel RNAi and compound screens identify thePDK1 pathway as a target for tamoxifen sensitization. Biochem J 417,361-370; Osborne, C. K., Bardou, V., Hopp, T. A., Chamness, G. C.,Hilsenbeck, S. G., Fuqua, S. A., Wong, J., Allred, D. C., Clark, G. M.,and Schiff, R. (2003). Role of the estrogen receptor coactivator AIB1(SRC-3) and HER-2/neu in tamoxifen resistance in breast cancer. J NatlCancer Inst 95, 353-361). Together these studies suggest that inhibitionof PKCζ activity may have beneficial therapeutic effects by acting as achemosensitiser to a wide array of commonly used chemotoxic agents inthe clinic.

Further evidence that small molecule inhibition of PKCζ could haveimportant therapeutic benefits has recently emerged from tumour modelsthat link PKCζ signalling to the mTOR pathway. PKCζ is constitutivelyactivated in follicular lymphoma and has been identified as a noveltarget for the anti-CD20 therapeutic antibody rituximab (Leseux, L.,Laurent, G., Laurent, C., Rigo, M., Blanc, A., Olive, D., and Bezombes,C. (2008). PKC zeta mTOR pathway: a new target for rituximab therapy infollicular lymphoma. Blood 111, 285-291). Rituximab inhibits follicularlymphoma proliferation by targeting a PKCζ-MAPK-mTOR pathway, suggestingthat PKCζ is both a target of Rituximab, and a key regulator of its'anti-leukaemic effect. Regulation of the mTOR/p70S6K pathway by PKCζ hasalso been implicated in the transition of prostate cancer cells to anandrogen-independent state (Inoue, T., Yoshida, T., Shimizu, Y.,Kobayashi, T., Yamasaki, T., Toda, Y., Segawa, T., Kamoto, T., Nakamura,E., and Ogawa, O. (2006). Requirement of androgen-dependent activationof protein kinase Czeta for androgen-dependent cell proliferation inLNCaP Cells and its roles in transition to androgen-independent cells.Mol Endocrinol 20, 3053-3069). Finally, mice containing a homozygousdeletion of Par4, a negative regulator of PKCζ, exhibit greatly enhancedPKCζ activity. These mice spontaneously develop tumours of the prostateand endometrium, and potentiate Ras-induced lung carcinogenesisconsistent with a role for PKCζ in lung cancer (Garcia-Cao, I., Duran,A., Collado, M., Carrascosa, M. J., Martin-Caballero, J., Flores, J. M.,Diaz-Meco, M. T., Moscat, J., and Serrano, M. (2005). Tumour-suppressionactivity of the proapoptotic regulator Par4.

The heterocycloalkylene group may contain,in addition to carbon atom(s), at least one nitrogen. For example, aheterocycloalkylene group may contain from 3 to 10 ring atoms; such asfrom 3 to 7 ring atoms. A heterocycloalkylene group may contain from 5to 7 ring atoms, such as 5 ring atoms, 6 ring atoms, or 7 ring atoms.Unless otherwise indicated, the foregoing heterocycloalkylene groups canbe C-attached and/or N-attached where such is possible and results inthe creation of a stable structure. A heterocycloalkylene group can alsoinclude ring systems substituted on ring carbons with one or more —OHfunctional groups (which may further tautomerize to give a ring C═Ogroup) and/or substituted on a ring sulfur atom by one (1) or two (2)oxygen atoms to give S═O or SO₂ groups, respectively, and/or substitutedon a ring phosphorus by an oxygen atom to give P═O.

-   “Heterocycloalkylalkyl” or “heterocycloalkylalkyl group” refers to    an alkyl group in which a hydrogen atom is replaced by a    heterocycloalkyl group, wherein alkyl group and heterocycloalkyl    group are as previously defined (i.e., heterocycloalkylalkyl-).    Heteroycloalkylalkyl groups can be substituted or unsubstituted.    Examples include, but are not limited to, pyrrolidinylmethyl    (C₄H₈NCH₂—).-   “Pharmaceutically acceptable” refers to physiologically tolerable    materials, which do not typically produce an allergic or other    untoward reaction, such as gastric upset, dizziness and the like,    when administered to a human.-   “Pharmaceutical composition” refers to a composition that can be    used to treat a disease, condition, or disorder in a human.-   “Pseudohalogen” refers to —OCN, —SCN, —CF₃, and —CN.-   “Stable” or “chemically stable” refers to a compound that is    sufficiently robust to be isolated to a useful degree of purity from    a reaction mixture. The present application is directed solely to    the preparation of stable compounds. When lists of alternative    substituents include members which, owing to valency requirements,    chemical stability, or other reasons, cannot be used to substitute a    particular group, the list is intended to be read in context to    include those members of the list that are suitable for substituting    the particular group. For example, R¹ can be C₁₋₆alkyl optionally    substituted by 1-13 R¹⁹; when R¹ is methyl, the methyl group is    optionally substituted by 1-3 R¹⁹.-   “Therapeutically effective amount” refers to an amount of a compound    sufficient to inhibit, halt, or cause an improvement in a disorder    or condition being treated in a particular subj ect or subject    population. For example in a human or other mammal, a    therapeutically effective amount can be determined experimentally in    a laboratory or clinical setting, or may be the amount required by    the guidelines of the United States Food and Drug Administration, or    equivalent foreign agency, for the particular disease and subject    being treated. It should be appreciated that determination of proper    dosage forms, dosage amounts, and routes of administration is within    the level of ordinary skill in the pharmaceutical and medical arts.-   “Treatment” refers to the acute or prophylactic diminishment or    alleviation of at least one symptom or characteristic associated or    caused by a disorder being treated. For example, treatment can    include diminishment of several symptoms of a disorder or complete    eradication of a disorder.    II. Compounds

The compounds of the present application are defined by the followingnumbered Embodiments. When a higher numbered Embodiment refers back tomultiple previous lower numbered Embodiments in the alternative andcontains a new limitation not present in the lower numbered Embodiments,the higher numbered Embodiment is intended to be an express descriptionof each and every one of the alternatives. For example, if Embodiment 2refers back to Embodiment 1 and contains a limitation not present inEmbodiment 1, Embodiment 3 refers back Embodiments 1 or 2 and contains alimitation(s) not present in Embodiments 1 or 2, and Embodiment 4 refersback to any of Embodiments 1-3 and contains a limitation(s) not presentin Embodiments 1, 2, or 3, then Embodiment 4 is intended to be anexplicit description of a genus having the limitations of Embodiments 1and 4, an explicit description of a genus having the limitations ofEmbodiments 2 and 4 (i.e., 1, 2, and 4), and an explicit description ofa genus having the limitations of Embodiments 3 and 4 (i.e., 1, 3, and4, and 1, 2, 3 and 4). By way of example, if Embodiment 1 is a compoundof formula (I) defining R⁷, R⁸ and R⁹ independently as alkyl or aryl,Embodiment 2 is a compound of Embodiment 1 defining R⁷ as alkyl,Embodiment 3 is a compound of Embodiments 1 or 2 defining R⁸ as alkyl,and Embodiment 4 is a compound of any of Embodiments 1-3 definining R⁹as alkyl, then Embodiment 4 is an explicit description of a genus havingthe limitations of Embodiments 1 and 4 (i.e., a compound of formula (I)in which R⁷ and R⁸ are alkyl or aryl, and R⁹ is alkyl), an explicitdescription of a genus having the limitations of Embodiments 2 and 4(i.e., a compound of formula (I) in which R⁸ is alkyl or aryl, and R⁷and R⁹ are alkyl), an explicit description of a genus having thelimitations of Embodiments 3 and 4 (i.e., a compound of formula (I) inwhich R⁷ is alkyl or aryl, and R⁸ and R⁹ are alkyl; and a compound offormula (I) in which R⁷, R⁸ and R⁹ are all alkyl). It should be noted inthis regard that when a higher numbered Embodiment refers to a lowernumbered Embodiment and contains limitations for a group(s) not presentin the lower numbered Embodiment, the higher numbered Embodiment shouldbe interpreted in context to ignore the missing group(s). For example,if Embodiment 1 recites a compound of formula (I) in which X is H,C₁₋₁₀alkyl, or —C(═O)R²⁸, Embodiment 2 recites a compound of Embodiment1 in which X is H or C₁₋₁₀alkyl, and Embodiment 3 recites a compound ofEmbodiments 1 or 2 in which R²⁸ is alkyl, then Embodiment 3 defines agenus having the limitations of Embodiments 1 and 3 and a genus havingthe limitation of Embodiments 2 and 3 (i.e., 1, 2, and 3). In the genusdefined by the limitations of Embodiments 2 and 3, X cannot be—C(═O)R²⁸; therefore this genus should be interpreted to ignore theEmbodiment 3 definition of R²⁸=alkyl (i.e., the genus of Embodiments 2and 3 has the same scope as the genus of Embodiment 2).

The compounds of the present application are defined herein usingstructural formulas that do not specifically recite the mass numbers orthe isotope ratios of the constituent atoms. It is intended that thepresent application includes compounds in which the constituent atomsare present in any ratio of isotope forms. For example, carbon atoms maybe present in any ratio of ¹²C, ¹³C, and ¹⁴C; hydrogen atoms may bepresent in any ratio of ¹H, ²H, and ³H; etc. Preferably, the constituentatoms in the compounds of the present application are present in theirnaturally occurring ratios of isotope forms.

General synthesis of8-substituted-1-yl-2-pyridin-4-yl-pyrido[3,4-d]pyrimidine derivatives ofgeneral formula [F-011] Scheme A3

4-Substituted 8-Chloro-2-pyridin-4-yl-pyrido[3,4-d]pyrimidin derivativesof general formula [F-010] were prepared by the reaction of a8-Chloro-2-pyridin-4-yl-pyrido[3,4-d]pyrimidin-4-ol derivative ofgeneral formula [F-009] with 2,4,6-triisopropylbenzenesulfonyl chloridein a polar aprotic solvent such as DMA, DMF, NMP with a tertiaryalkylamine base such as Et₃N, DIPEA or NMM and a catalytic amount ofDMAP. The intermediate6,7-substituted-(2,4,6-triisopropyl-benzenesulfonicacid)-8-Chloro-2-pyridin-4-yl-pyrido[3,4-d]pyrimidini-4-yl ester wasthen reacted with a primary or secondary amino derivative, of generalformula [F-003], in a polar aprotic solvent such as DMA, DMF, NMP in thepresence of a tertiary amine base such as Et₃N, DIPEA or NMM at ambienttemperature. After reaction work up, typically by a liquid-liquidextraction or purification by acidic ion exchange catch-release, thecrude reaction product was purified by normal phase chromatography orreverse phase preparative HPLC. The 4-Substituted8-Chloro-2-pyridin-4-yl-pyrido[3,4-d]pyrimidin derivatives of generalformula [F-010] were reacted in a Suzuki type reaction utilising asuitable boronic acid or boronic ester, of general formula [F-012], apalladium catalyst such as Pd(PPh₃)₄ or Pd(PPh₃)₂Cl₂ α base such asEt₃N, KOH, Na₂CO₃ or NaOH in a polar solvent such as EtOH, THF, DMA ordioxane at high temperature either by heating thermally or using amicrowave reactor. After reaction work up, typically by a liquid-liquidextraction or purification by acidic ion exchange catch-release, theN-Boc derivatives were deprotected under acidic conditions with a strongacid such as TFA, TCA, methanesulfonic acid, HCl or H₂SO₄ in a solventsuch as DCM, DCE, THF, EtOH or MeOH and the crude reaction product waspurified by normal phase chromatography or reverse phase preparativeHPLC.

Biology

PKCι IC₅₀ Assay

Assays are based on the ability of PKCι to phosphorylate a commerciallyavailable peptide substrate in vitro. The peptide substrate is FAM-PKCεpseudopeptide derived peptide, and comprises the amino acid sequence5FAM-ERMRPRKRQGSVRRRV-NH₂. Recombinant, full-length human PKCι expressedin Sf21 insect cells is also commercially available. Recombinant,kinase-domain human PKCι is expressed and purified in-house.

The procedure below explains how dose response curves for inhibitors ofPKCι are obtained. The screen described is for a 384 well format but theassay can be adapted to 1536 or other formats as required.

Compounds to be tested are dissolved in 100% DMSO. Compounds are dilutedas required to give a final concentration of 4% DMSO (v/v) in the assay.1 μl is plated into 384 well black low-binding flat bottomed assayplates which are used immediately. Dilutions and additions of compoundto assay plates are carried out using Matrix WellMate® and MatrixPlateMate® Plus liquid handling systems.

On the day of the screen PKCι/substrate working solution, and ATPworking solution, are prepared in buffer containing 20 mM tris-HClpH7.5, 10 mM MgCl₂, 0.01% Triton X100, 250 μM EGTA and 1 mM DTT. Thefinal concentration of PKCι used varies depending on the batch ofprotein but is typically 15 pM. The final concentration of peptidesubstrate in the assay is 100 nM. ATP is used at a final concentrationof 150 μM or 25 μM in the assays containing full-length or kinase-domainPKCι respectively, which corresponds to five times or equal to the K_(M)^(APP) for ATP for each enzyme, respectively. The final bufferconcentration in the assay is 18 mM tris-HCl pH7.5, 9 mM MgCl₂, 0.009%Triton X100, 225 μM EGTA and 0.9 mM DTT. Relevant controls are included,namely no compound and no enzyme. 5 μl PKCι/substrate working solutionat 30 pM and 200 nM, respectively, is added to the wells, followed by 4μl ATP working solution at 375 μM or 62.5 μM for full-length orkinase-domain PKCι respectively, using a 16 channel Matrix pipette. Thereaction is allowed to incubate for 60 minutes at room temperature,before the reaction is stopped and developed by the addition of 20 μlIMAP™ development reagent (Molecular Devices). IMAP development reagentconsists of 0.25% (v/v) IMAP progressive binding reagent, 17% (v/v) IMAPprogressive binding buffer A and 3% (v/v) IMAP progressive bindingbuffer B. The plates are then incubated for 2 hours at room temperaturebefore being read using an appropriate plate reader, for example aMolecular Devices HT Analyst or a BMG Pherastar. Plates are read using afluorescence polarisation protocol with excitation at 485 nm andemission at 530 nm, and dichroic mirror at 505 nm.

Percentage inhibition values are calculated from fluorescencepolarisation values, using the no compound and no enzyme control valuesas 0% and 100% inhibition, respectively. IC₅₀ determination is performedwith ExcelFit software (IDBS) using curve fit 205. Z′ factors aredetermined for each plate tested and are all above 0.5.
